Jehovah delegated all his creative works to Jesus, his 'word', meaning spokesman.

1:15 "He is the image of the invisible God, the firstborn of all creation; For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist. Col 1:15

Quoting: DGN

Jesus was/is Jehovah. The firstborn as the following verses explain means he created all life. Jesus/God was not created.Only God can create.

This is why other passages Jesus explains he is the "I Am" for which the Jews took up stones to stone him for blasphemy for claiming to be God. Thus the definition of "blasphemy" is one who claims to be God. There are two examples of this in scripture. And other passages that tell us God came to earth. If you have a proper Bible.
